Phase 1 — live POI + neighborhood score on project detail
- du-an-detail-client fetches `/analytics/pois/nearby` + `/analytics/neighborhoods/:district/score`
- Falls back to admin-entered `project.pois` / `neighborhoodScores` when endpoint returns nothing
- Adds total-score badge next to the radar chart (matches listings)
Phase 2 — project personas derivation (`lib/project-personas.ts`)
- Derives 8 personas from project-specific signals: property-type mix, amenity keywords,
developer reputation, completion timing, status, live score + POIs
- Merges admin-authored `suitableFor` chips (badged "Chủ đầu tư chọn") with derived chips
- `composeWhyThisProject()` narrative used as fallback when admin hasn't authored one;
badged "Tự động tổng hợp" so users know it's derived
Phase 3 — AI advisor for projects
- Extract shared Anthropic transport + JSON parsers to
`analytics/application/queries/_shared/ai-json-client.ts` (dual auth: x-api-key +
Bearer for proxy gateways)
- Refactor `GetListingAiAdviceHandler` to use the shared client
- New `GetProjectAiAdviceHandler` (CQRS) pulls project detail + optional POIs + score,
builds project-flavored prompt, returns `{ advice: { summary, pros, cons, suitableFor } }`.
No valuation block — project price is a range, not a single unit.
- `POST /analytics/projects/:id/ai-advice` endpoint (JWT-guarded)
- `ErrorCode.PROJECT_NOT_FOUND` added
- Frontend: `ProjectAiAdviceCard` mirrors listings card minus valuation, with loading /
not-configured (503) / error states; dedupes AI-suggested personas against existing chips
Phase 4 — Mapbox LocationPicker in project create form
- New project page now renders `<LocationPicker>` with Vietnam-scoped geocoder; click /
drag / search autofills lat+lng and (when empty) address/ward/district/city
- Edit page notes location immutability — backend `UpdateProjectCommand` does not yet
accept lat/lng/address mutations (follow-up needed to enable editing coords)

New endpoint POST /analytics/listings/:id/ai-advice (JwtAuthGuard).
Orchestrates a single-listing AI analysis in Vietnamese via Anthropic
Claude, using the key/URL/model configured in admin settings.
Backend
-------
- New CQRS: get-listing-ai-advice/{query,handler}.ts under analytics.
Injects LISTING_REPOSITORY, QueryBus (for nearby POIs + neighborhood
score), SystemSettingsService (from @modules/admin), LoggerService.
- Controller @Post('listings/:id/ai-advice') in analytics.controller.ts.
- analytics.module.ts now imports ListingsModule + AdminModule.
- Anthropic call: native fetch to ${apiUrl}/messages with
x-api-key + anthropic-version: 2023-06-01 +
anthropic-beta: prompt-caching-2024-07-31. System block marked
cache_control:{type:'ephemeral'} for cheap subsequent cache hits.
30s AbortController timeout.
- Response validation without adding zod to the API workspace —
lightweight isRecord/asInt/asString/asStringArray helpers.
Strips ```json fences before JSON.parse.
- Error handling:
* 503 AI_NOT_CONFIGURED when the admin hasn't saved an API key.
* 502 AI_PROVIDER_ERROR on non-2xx, parse failure, or timeout.
* Key never logged.
* POI / score fetch failures are soft — prompt is built without
them and the model still runs.
- New error codes AI_NOT_CONFIGURED / AI_PROVIDER_ERROR in
shared/domain/error-codes.ts.
Response shape (returned unchanged to the client):
```
{
valuation: { estimateVND, lowVND, highVND, confidence, rationale },
advice: { summary, pros[], cons[], suitableFor[] },
model, cacheHit
}
```
Frontend
--------
- analytics-api.ts: exports AiConfidence, ListingAiValuation,
ListingAiAdviceBody, ListingAiAdvice + getListingAiAdvice(id).
- New components/listings/ai-advice-cards.tsx.
* Default state: outline <Button><Sparkles/> Xem phân tích AI</Button>
* On click: useMutation fires + skeleton with Sparkles spinner.
* On success: two sidebar cards:
- "AI định giá" — big mid VND, low–high range, Low/Medium/High
confidence badge, rationale with line-clamp-3.
- "AI nhận định" — 2-sentence summary + two-column Pros/Cons
(Check / AlertTriangle icons) + "AI gợi ý" chips for extra
personas, plus a "Làm mới" link that re-triggers the mutation.
* 503 → amber banner. ADMIN users see a link to /admin/settings/ai.
* Other errors → red banner with retry.
- listing-detail-client.tsx mounts <AiAdviceCards listingId=... /> in
the sidebar between the social-share card and the stats block.
Existing <AiEstimateButton> kept untouched next to it.
Constraints preserved
---------------------
- No new npm packages; no @anthropic-ai/sdk.
- Runtime imports for NestJS DI classes.
- API key read at request time only — nothing persists it outside
SystemSetting.
Verification
------------
- API typecheck clean; 1975 / 1975 tests pass.
- Web typecheck clean in touched files; 624 / 624 tests pass.
- AiAdviceCards spec-mocked in listing-detail-client.spec so
QueryClientProvider isn't required.
User can now set their Anthropic key via /admin/settings/ai and click
"Xem phân tích AI" on any listing detail to get valuation + advice.
